Please contribute to the list on http://www.nanog.org/filter.html by sending mail to mailto:www@www.merit.edu and this mailing list mailto:nanog@merit.edu I'd say the list should not only include hard facts like URLs to ISP publications, but also information like your personal experiences, known issues caused by publicly unconfirmed route filtering etc... Pointers to better sources of such information are also appreciated... thanks joerg P.S. Yes, I have (also) selfish reasons to ask for that...
